Jarecki uncovered an apparently damning piece of evidence in the unsolved 2000 murder of Durst's friend Susan Berman -- a letter Durst wrote to Berman in 1999 addressed to "Beverley [sic] Hills." Berman's killer wrote an anonymous letter to police, also addressed to "Beverley [sic] Hills."

After Jarecki sprang the evidence on Durst, the latter denied responsibility but later -- not realizing his mic was still on -- Durst muttered to himself, "What the hell did I do? Killed them all, of course."

Hours before the airing of the sixth and final episode of The Jinx," in which Jarecki confronted Durst with the letter, the FBI arrested Durst on a first-degree murder charge, based on the newly-uncovered evidence.
